2/9/15Today’s Objective:8.G.6 Explain a proof of the Pythagorean Theorem and its converse. 8.G.7 Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real world and mathematical problems in two and three dimensions.
Today we will be focusing on word problems using the Pythagorean
Theorem.What is the first thing you do when
you are given a word problem?
Problem OneHow long must a wire be to reach
from the top of a 15 meter telephone pole to a point on the
ground 10 meters from the foot of the pole? Jot down what you think
you should do.
